As another important nonclassical property we examine the
quadrature squeezing. For this purpose we first consider the
conventional quadrature operators \(\hat{X}_a\)  and \(\hat{Y}_a\) 
defined in terms of nondeformed operators \(\hat{a}\)  and
\(\hat{a}^\dag \)  as [1]}
\(\hat{X}_{a}=\frac{1}{2}(\hat{a}e^{i\phi }+\hat{a}^{\dag }e^{-i\phi })\hspace{28.45274pt}\hat{Y}_a=\frac{1}{2i}(\hat{a}e^{i\phi }-\hat{a}^{\dag }e^{-i\phi }).\)
